how to do adaptation

how to do adaptation

[Susanne G. Loeber]

Hi,
I am looking for ways to adapt the layout and content of texts while
using ConTeXt. Put simple: show part of a text and sort these parts
based on data from the user and the author (.dat file). The biggest
problem is not knowing which part of the text will be first and how
many parts will be shown.

So far, I am trying to get a hang of \setupdocument
(https://wiki.contextgarden.net/Project_structure), \startmode
(https://wiki.contextgarden.net/Modes), \definecolor
(https://wiki.contextgarden.net/Color) and \defineparagraphs
(https://wiki.contextgarden.net/Command/defineparagraphs)

I hope there are more ways to create adaptation.

I would also like to know whether certain combination don't work
together. For example, I cannot seem to get \doifmodeelse to work
inside a \defineparagraphs environment.

\defineparagraphs[BLpar][n=2, frame=on]
\setupparagraphs [BLpar][1][width=\dimexpr.3\textwidth]

\starttext

% Working
\enablemode[asg]

\doifmodeelse{asg} {\par First sentence} {\par Second sentence}
\disablemode[asg]
\doifmodeelse{asg} {\par First sentence} {\par Second sentence}
\doifnotmode{asg} {\par Third sentence}

% Not working
\enablemode[one]

\startBLpar
\doifmodeelse{one} {First sentence} {Second sentence} \disablemode[one]
\BLpar
% \disablemode[one] %% not helping
TOP1 paragraphs
\stopBLpar
% \disablemode[one] %% needed to make the example work

\startBLpar
\doifmodeelse{one} {First sentence} {Second sentence}
\BLpar
TOP2 paragraphs
\stopBLpar

\startBLpar
\doifnotmode{one} {Third sentence}
\BLpar
TOP3 paragraphs
\stopBLpar

\stoptext


Kind regards,
Susanne G. Loeber

Can you ask a separate question for each individual problem.

When you enable or disable a mode the state is local to the current group,
e.g. the state at the begin of a environment will be the same at the end
and changes in the environment are local to it. In most document this isn't
a problem because you enable/disable a mode at the begin of the document
and use the state at the whole document.

In your case you want the changed state to remain after the environment
has ended, to do this you have to use \globalenablemode[...] and
\globaldisablemode[...].
